ABSTRACT Photo-thermo-refractive (PTR) glass is an optically transparent photosensitive
multicomponent silicate glass. UV-exposure produces silver nanoclusters, and NaF …

Over the past few decades, the rapid development of ultrafast lasers, such as femtosecond
lasers and picosecond lasers, has opened up new avenues for material processing due to …

There are still some uncertainties in the origin of photo-thermo-induced refractive index
change in PTR glass. On one side, according to Nikonorov NV it is assumed to be due to …

Permanent binary phase masks with planar surfaces and high tolerance to laser radiation
are recorded in the volume of photo-thermo-refractive glass using the contact copying …

Photosensitivity in photo-thermo-refractive (PTR) glass can be triggered by UV and near-
infrared fs laser irradiation. Here we focus on the nonlinear photochemical process triggered …

The paper presents an overview of the benefits of recording phase masks into the bulk of
photo-thermo-refractive glass. We demonstrate that both binary and gray-scale phase masks …

We show that photoionization of wide band gap silicate glasses by infrared ultrashort laser
pulses can occur without laser-induced damage. Two glasses are studied, fused silica and a …

When an ultrashort laser pulse is focused inside the bulk of a transparent material,
filamentation occurs as a result of the dynamic balance between the Kerr self-focusing and …

Microfluidic chips and optical elements can be fabricated based on the nonlinear
photosensitivity in photo–thermo–refractive (PTR) glass by controlling the growth of …

Experimental and modeled dependencies of the induced refractive index on dosage of UV
exposure in photo-thermo-refractive glass for different thermal treatment regimes are …
